SYNOPSIS

DESCRIPTION

XmDropSiteRegister identifies the
specified widget or gadget as a drop site and sets resource values that define
the drop site's behavior. The routine assigns default values to any resources
that are not specified in the argument list. The toolkit generates a warning
message if a drop site is registered with XmNdropSiteActivity set to XmDROP_SITE_ACTIVE and the XmNdropProc resource is NULL.

If the drop site is a descendant of a widget that is registered as a
drop site, the XmNdropSiteType resource
of the ancestor drop site must be specified as XmDROP_SITE_COMPOSITE. The ancestor must be registered before the descendant. The drop
site is stacked above all other sibling drop sites already registered.
Specifies the ID of the widget to be registered.
Specifies the argument list.
Specifies the number of attribute/value pairs in the argument
list (arglist).
